Description

Technical Field

[0001] This utility model relates to the field of fiber manufacturing technology, and in particular to a water filtration device for the head of a ceramic fiber product. Background Technology

[0002] The ceramic fiber product die head filtration device is a solid-liquid separation equipment used in the production of ceramic fiber products. Through specific structures (such as mesh belts and discharge cylinders) and processes (such as vacuum filtration or mechanical extrusion), it effectively removes water from the ceramic fiber slurry while retaining the solid components of the fibers, forming a uniform wet blank. This provides a suitable raw material form for subsequent drying, sintering, and other processes. The main function of this device is to achieve efficient dewatering of the slurry, improving the production efficiency and product quality of fiber products. The ceramic fiber product die head filtration device mainly consists of a mesh belt, a water tank, and a water pool. Drainage pipes connect the water tank and the water pool, and a vacuum pipe connects the water tank to the vacuum pump. The mesh belt, positioned above the water tank, filters the water. See [link to details]. Figure 4 ;

[0003] When processing thin fiber products, the vacuum valve is closed and no vacuuming is required. Water will fill the vacuum pipe and drainage pipe, and there is a water seal below the drainage pipe. At this time, there is no pressure difference, and water will continue to be pushed down from the top of the conveyor belt under atmospheric pressure, causing the water level on the conveyor belt to drop and affecting product quality. When processing high-density fiber products, the vacuum valve needs to be opened to create a vacuum. Water will flow into the vacuum pipe and drainage pipe. If the vacuum pipe absorbs too much water, it will affect the suction force, and the water on the conveyor belt will not be able to come down. It will continue to extend forward, exceed the guardrail and flow down, thus making production impossible. Therefore, this utility model proposes a water filtration device for the head of a ceramic fiber product machine to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a ceramic fiber product machine head filtration device. This device adds an exhaust pipe with an exhaust valve below the vacuum pipe. When processing thin fiber products, the exhaust valve is opened to connect the vacuum pipe to the outside environment, eliminating the pressure difference and thus solving the problem.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a water filtration device for ceramic fiber product machine head, including a water tank, a water pool and a vacuum pump, wherein a water filtration assembly is provided above the water tank, and a drain pipe is connected to the lower side of one side of the water tank, and the output end of the drain pipe extends into the interior of the water pool.

[0006] The vacuum pump has a vacuum pipe connected to its input end. The input end of the vacuum pipe passes through the bottom of the water tank and is higher than the bottom of the water tank. The input end of the vacuum pipe is connected to the inside of the water tank. A funnel cap is provided above the input end of the vacuum pipe. An exhaust pipe is connected to the side of the vacuum pipe. Both the vacuum pipe and the exhaust pipe have opening and closing functions.

[0007] A further improvement is that the water filtration assembly includes a mesh belt and a discharge cylinder, with the mesh belt positioned above the water tank and the discharge cylinder positioned on one side of the mesh belt.

[0008] A further improvement is that a vacuum valve is provided on the vacuum pipeline, and the vacuum valve is located between the exhaust pipeline and the vacuum pump.

[0009] A further improvement is that an exhaust valve is provided on the exhaust pipe.

[0010] A further improvement is that a connecting rod is provided on the outside of the vacuum pipe input end, and multiple sets of connecting rods are provided, with the funnel cap connected to the connecting rod.

[0011] A further improvement is that the output end of the drainage pipe extends to the lower part of the pool, and the output end of the drainage pipe forms a water seal with the water inside the pool.

[0012] A further improvement is that the input end of the vacuum pipe is higher than the connection point between the drainage pipe and the water tank.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model adds an exhaust pipe with an exhaust valve under the vacuum pipe. When processing thin fiber products, the exhaust valve is opened to connect the vacuum pipe with the outside world, eliminate the pressure difference, and thus solve the problem.

[0015] 2. This utility model extends the vacuum pipe inlet end in the water tank by a section and adds a funnel cap. When processing high-density fiber products, the vacuum valve is opened to draw a vacuum, and the exhaust valve is closed. Due to the high position of the vacuum pipe inlet end and the effect of the funnel cap, water is prevented from being directly drawn into the vacuum pipe, which would affect the vacuum force, thus solving the problem.

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] Example 1

[0023] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a ceramic fiber product head water filtration device, including a water tank 1, a water pool 2 and a vacuum pump 3. A water filtration assembly is provided above the water tank 1, and a drain pipe 5 is connected to the lower side of one side of the water tank 1, and the output end of the drain pipe 5 extends into the interior of the water pool 2.

[0024] The vacuum pump 3 has a vacuum pipe 4 connected to its input end. The input end of the vacuum pipe 4 passes through the bottom of the water tank 1 and is higher than the bottom of the interior of the water tank 1. The input end of the vacuum pipe 4 is connected to the interior of the water tank 1. A funnel cap 7 is provided above the input end of the vacuum pipe 4. An exhaust pipe 6 is connected to the side of the vacuum pipe 4. Both the vacuum pipe 4 and the exhaust pipe 6 have opening and closing functions. In use, an exhaust pipe 6 with an exhaust valve 10 is added below the vacuum pipe 4. When processing thin fiber products, the exhaust valve 10 is opened to connect the vacuum pipe 4 to the outside, eliminating the pressure difference and thus solving the problem. Furthermore, the input end of the vacuum pipe 4 inside the water tank 1 is extended and a funnel cap 7 is added. When processing high-density fiber products, the vacuum valve 10 is opened to draw a vacuum, and the exhaust valve 11 is closed. Due to the high position of the input end of the vacuum pipe 4 and the function of the funnel cap 7, water is prevented from being directly drawn into the vacuum pipe 4, affecting the vacuum force, thus solving the problem. The funnel cap 7 also prevents the top from collapsing.

[0025] The filtration assembly includes a mesh belt 8 and a discharge cylinder 9. The mesh belt 8 is positioned above the water tank 1, and the discharge cylinder 9 is located on one side of the mesh belt 8. In use, after the slurry is spread on the surface of the mesh belt, the liquid is discharged through the mesh holes under vacuum suction or mechanical extrusion, while the solid fibers are trapped to form a wet blank. The discharge cylinder 9 is located at the end of the mesh belt 8, close to its underside, and is used to receive residual slurry that has not been completely dewatered or backwash wastewater.

[0026] A vacuum valve 10 is installed on the vacuum pipe 4, located between the exhaust pipe 6 and the vacuum pump 3. An exhaust valve 11 is installed on the exhaust pipe 6. In use, an exhaust pipe 6 with the exhaust valve 10 is added below the vacuum pipe 4. When processing thin fiber products, the exhaust valve 10 is opened to connect the vacuum pipe 4 to the outside, eliminating pressure differences and thus solving the problem. Furthermore, a funnel cap 7 is added to the inlet end of the vacuum pipe 4 within the water tank 1. When processing dense fiber products, the vacuum valve 10 is opened to create a vacuum, and the exhaust valve 11 is closed. Due to the elevated position of the inlet end of the vacuum pipe 4 and the effect of the funnel cap 7, water is prevented from being directly drawn into the vacuum pipe 4, thus avoiding interference with the vacuum pumping force and solving the problem.

[0027] A connecting rod 12 is provided on the outer side of the input end of the vacuum pipe 4, and multiple sets of connecting rods 12 are provided. The funnel cap 7 is connected to the connecting rod 12. The funnel cap 7 covers the input end of the vacuum pipe 4 and does not affect the connection of the input end of the vacuum pipe 4.

[0028] Example 2

[0029] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a ceramic fiber product head water filtration device, including a water tank 1, a water pool 2 and a vacuum pump 3. A water filtration assembly is provided above the water tank 1, and a drain pipe 5 is connected to the lower side of one side of the water tank 1, and the output end of the drain pipe 5 extends into the interior of the water pool 2.

[0030] The vacuum pump 3 has a vacuum pipe 4 connected to its input end. The input end of the vacuum pipe 4 passes through the bottom of the water tank 1 and is higher than the bottom of the interior of the water tank 1. The input end of the vacuum pipe 4 is connected to the interior of the water tank 1. A funnel cap 7 is provided above the input end of the vacuum pipe 4. An exhaust pipe 6 is connected to the side of the vacuum pipe 4. Both the vacuum pipe 4 and the exhaust pipe 6 have opening and closing functions. In use, an exhaust pipe 6 with an exhaust valve 10 is added below the vacuum pipe 4. When processing thin fiber products, the exhaust valve 10 is opened to connect the vacuum pipe 4 to the outside, eliminating the pressure difference and thus solving the problem. Furthermore, the input end of the vacuum pipe 4 inside the water tank 1 is extended and a funnel cap 7 is added. When processing high-density fiber products, the vacuum valve 10 is opened to draw a vacuum, and the exhaust valve 11 is closed. Due to the high position of the input end of the vacuum pipe 4 and the function of the funnel cap 7, water is prevented from being directly drawn into the vacuum pipe 4, affecting the vacuum force, thus solving the problem. The funnel cap 7 also prevents the top from collapsing.

[0031] The output end of the drainage pipe 5 extends to the lower part of the interior of the water tank 2, and a water seal is formed by the water inside the water tank 2 at the output end of the drainage pipe 5. The input end of the vacuum pipe 4 is higher than the connection point between the drainage pipe 5 and the water tank 1. When processing thin fiber products, the vacuum valve 10 is closed and no vacuuming is required. The water seal is below the drainage pipe. At this time, the exhaust valve 10 is opened to connect the vacuum pipe 4 to the outside and eliminate the pressure difference. The input end of the vacuum pipe 4 in the water tank 1 is extended to a higher position and a funnel cap 7 is added. When processing high-density fiber products, the vacuum valve 10 is opened to draw a vacuum, and the exhaust valve 11 is closed. Due to the high position of the input end of the vacuum pipe 4 and the effect of the funnel cap 7, water is prevented from being directly drawn into the vacuum pipe 4, which would affect the vacuum pumping force.

[0032] The ceramic fiber product machine head filtration device adds an exhaust pipe 6 with an exhaust valve 10 below the vacuum pipe 4. When processing thin fiber products, the exhaust valve 10 is opened to connect the vacuum pipe 4 to the outside, eliminating the pressure difference and thus solving the problem. Furthermore, a funnel cap 7 is added to the inlet end of the vacuum pipe 4 inside the water tank 1. When processing dense fiber products, the vacuum valve 10 is opened to create a vacuum, and the exhaust valve 11 is closed. Due to the high position of the inlet end of the vacuum pipe 4 and the effect of the funnel cap 7, water is prevented from being directly drawn into the vacuum pipe 4, affecting the vacuum suction force, thus solving the problem. The funnel cap 7 also prevents the top from collapsing.
